Got it fixed. It's at 8 GB of RAM now. :-D It wasn't properly seated, I knew it.
That is what I thought, I did had trouble seating second stick. Struggling because I could tell that it was not seated properly. Once I get "Snapped" Pah! and ran my MAC Mini, and it was CHAMP, I am sure you already notice that too. I am not sure but very likely my next computer will be MAC. Right now my computer is PC, my wife is MAC mini and do use her so I can understand how MAC works and helps me at my work.
It's far faster than it was with only 2 GB of RAM. More responsive and no more caching. Apps open faster and response quicker as well. Now, I can leave some apps open without worrying about slowing down.
When I purchased my moms all-in-one computer from HP. I made sure to include 6GB. 8 was available but I figured, 6 would be sufficient considering my parents only browse the web. It's not like they have PS suites installed or anything that eats memory like crazy.
